Trees are more than just part of our natural landscape. They provide shelter and food for wildlife. They absorb carbon dioxide and produce breathable air. And one of the best things about trees is that they add to the beauty of the world.
Just like humans, trees need water to survive--and they drink a lot of it. In a single day, a large tree can consume 100 gallons of water out of the ground and discharge it into the air as oxygen and water vapor. Keep in mind that many conditions play a role such as the size of the tree, species of the tree, humidity, temperatures, sun exposure, etc.
Strategically planting trees and shrubs can save you up to 25 percent on your energy bills. Not only do they provide shade in the summer, but serve as a windbreak in the winter, too.
Trees are able to communicate with each other and themselves against attacking insects. Scientists have found that trees can flood their leaves with chemicals called phenolics when the insects begin their raid. They can also signal danger to other trees so they can start their own defense.
